The product code in the NDC identifies which of the following?

The product code in the National Drug Code (NDC) specifically identifies the drug's strength and dosage form. The NDC is a unique identifier for drugs in the United States, and it is structured in three segments. The first segment identifies the labeler or manufacturer, the second segment identifies the specific product (which includes the strength and dosage form), and the third segment indicates the packaging type.

By focusing on the product code, it becomes clear that this segment allows healthcare professionals and pharmacists to distinguish between different formulations and dosages of the same drug. For example, the same medication might be available in both tablet and liquid forms, or in different strengths; the product code will provide the necessary information to differentiate these products effectively. This specificity is crucial in ensuring safe and accurate dispensing of medications.
